The relationship between the mean Fulton’s condition and form factors of 12 marine species (N=209 fish specimens) caught in the Zadar area (middle eastern Adriatic) was analysed. The lowest mean condition factor (K = 0.6329) referred to the elongated Trachinus draco, while the highest one (K = 1.7758) referred to the deep-bodied Scorpaena porcus. The correlation between the mean Fulton’s condition and form factors of these 12 populations was highly significant (K = 0.404 + 0.663 a3.0; r2 = 0.815; P < 0.01). Including more species in the calculation would give even more accurate results.

Emerita emeritus is an abundant species in Bengkulu coastal waters, but the knowledge of its reproductive biology is poor. The present study was conducted to elucidate the reproductive aspects of ovigerous female E. emeritus, including fecundity, egg volume and reproductive output. This study was conducted between January 2015 and January 2016 in Bengkulu coastal waters, Indonesia. Samples were collected manually using shovels and hands. The results showed that ovigerous females occurred every month. Fecundity increased significantly in ovigerous females proportional to the size. No correlation was shown between sea surface temperature and egg production. Fecundity and reproductive output decreased throughout the embryonic development.
The length-weight relationship, condition factor, fecundity, gonadosomatic and hepatosomatic indices of Parachanna obscura from the Anambra River were determined between December 2015 and June 2016. Eighty-three live samples of P. obscura were obtained from fishermen. Descriptive statistics, correlation and regression analysis were used to analyze the obtained data. The length-weight relationship had R values of 0.933, 0.843 and 0.896 for male, female and combined sexes, respectively. The b value of 3.133 for male and 2.674 for female were not significantly different (P>0.05). Mean condition factors of 0.89±0.33 and 0.80±0.21 were obtained for female and male, respectively. The largest number of eggs (10,965) was found in a female with the body weight of 154 g, gonad weight of 9.1 g and egg size of 1.3 mm, while the least fecund female with 1820 eggs weighed (94 g) and had a gonad weight 2.1 g with egg size of 1.0 mm. The hepatosomatic indices ranged between 0.55±0.20 and 0.64±0.29 in both male and female, respectively, while female gonadosomatic index average was 2.05±1.44. There was a positive correlation between fecundity and gonad weight.

The relationship between morphological traits and feeding ecology of the only two tilapiine cichlids (Sarotherodon galilaeus and Oreochromis niloticus) in Lake Geriyo, northeastern Nigeria, was examined. Stomach contents of 504 individuals were examined and analyzed to relate morphological differences of each species to its dietary preferences. Eleven ecological relevant morphological variables, including total length, standard length, head length, body depth, eye diameter, pectoral spine length, pelvic spine length, dorsal fin ray count, dorsal spine count and anal fin ray count, were also measured and subjected to Principal coordinate analysis (PCoA) to relate morphological differences of each species to its dietary preferences. The PCoA (using Euclidean distance) revealed a large morphological distance between species indicating adaptation for different spatial and vertical distributions within the lake. Furthermore, the correlation of these morphological differences with particular diet categories suggests a potential for specialized trophic tendencies, however, the high occurrence of two major food types (macrophytes and plankton) in stomach contents of both species indicate generalist trophic tendencies. While a high trophic overlap index (0.98) was recorded for both species, the trophic niche breadth was higher for S. galilaeus (4.18±0.32), compared to O. niloticus (3.33±0.24). Despite the large morphological differences of both tilapias, the high trophic overlaps indicate limited food options within Lake Geriyo. In addition, the successful coexistence of the tilapias in the face of limited food resources indicates suitable partitioning of food resources in the lake.
